Study Summary
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
Primary Outcome
Decision conflict scale (DCS) is calculated from 16 items, with each item ranging from 0 (strongly agree) to 4 (strongly disagree). The total score is reported on a 0-100 scale by summing all responses, dividing by 16 and multiplying by 25. Higher scores represent greater levels of uncertainty in decision-making (higher decision conflict = worse outcome), and interventions often aim to reduce decision conflict (lower decision conflict = greater likelihood of implementing a decision = better outc
